Background and purpose: Vibration caused by ventilation systems in buildings is one of the harmful physical factors that can cause harm to residents. Therefore, measuring and controlling vibration is important. Materials and Methods:  In the first step of the study, the vibration accelerometer was placed on the base of a fan where the vibrations were sent toward the duct wall. A vibration asse...

WAVO consists of a PoSC micro-computer, an accelerometer and a 16x16 matrix LED and express moving waves with LED. These waves are calculated by Wave Equation in real-time. Therefore, people can feel beautiful moving of lights which this equation makes. Yet, people can enjoy wave interaction as WAVO has an accelerometer. Interacting with people, this art work notices them fascinating aspects of...

A single-mask lateral tunneling accelerometer with integrated tip has been developed and characterized. High aspect ratio single-crystal silicon springs provide high resolution, wide operating bandwidth, and excellent isolation from off-axis stimuli. In this paper, we present the first such device implementing the SCREAM [1] process technology. We focus on the advantages that this technology af...

As various smart devices are introduced, the application software for analyzing the pattern and the quantity of exercise is addressed as a promising smart-phone application. In this paper, we propose a classification scheme of ambulatory movements with barometer and accelerometer of a smart-phone. According to the experimental results, the difference of barometer datum can provide the character...
